"WRENCH.

' Specification of Letters Patent.

Patented May as, 1922.

Application filed August 17, 1920. Serial No. 404,076.

. J '0 aZZ cohom it may concern Gofl's, in the county of Nemaha andState of Kansas, have invented new and useful Improvements in Wrenches,of which the following is a specification.

The object of my present invention is the provision of a wrench,designed more particularly for automobile work and possessed of a widerange of utility.

To the attainment of the foregoing the invention consists in theimprovements as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is aview showing one use of which my novel wrench may be put.

Figure 2 is a section taken in the plane indicated by the line 22 ofFigure 1, looking toward the left.

Figure 3 is a detail section taken at right angles to Figure 2 and inthe plane indicated by the line 38 of Figure 1.

Figure 4 is a detail section taken on the line 4-4 of Figure 1. I

Figure 5 comprises disconnected views ofsocket members of differenttypes from those shown in Figure 1 and which may be used interchangeablyin the wrench. Any desired number of auxiliary socket members ofdifierent types may be provided for use interchangeably in the wrench towiden the range of usefulness thereof.

. Figure 6 is a view showing the adaptability of a portion of the wrenchto be used as a socket wrench.

Figure 7 is a view like Figure 6 but showing the wrench adapted for useas an efficient. screw driver.

Figures 8 9 and 10 are detail views illustrative of the manner in whichthe T-head is detachably secured on the end of the shaft comprised inthe wrench.

Figure 11 is a detail section on the line 11--11 of Figure 1-.

Similar numerals of reference designate corresponding parts in all ofthe views of the drawings.

Among other elements my novel wrench comprises a frame. The said frameis made up of lapped bars 1 and 2. The-bar 1 is provided at 3 with atransverse aperture, and is also provided at one end with an arm 4 thatreaches at right angles therefrom and is provided with a circularaperture 5. The

other bar 2 is longitudinally slotted at 6, is provided at 7 with a loopthat loosely recelves the bar 1, and is providedat its opposite end withan angular arm 8 in which is an aperture 9, of angular configuration,Figure 4, said aperture 9 being arranged in alinement with the beforementioned aperture 5. The bars 1 and 2 are adjustably connected throughthe medium of a headed and threaded bolt 10, and a wing nut 11.Manifestly by virtue of this provision the lapped bars 1 and 2 may beadjustably fixed together to determine the distance between the arms 4and 9 accordin to the work to be done. In other words t e frame may beincreased or diminished in length as desired and then the lapped bars 1and 2 may be adjustably fixed with respect to each other. It will alsobe noted in this connection that the lapped bars reinforced and lendincreased strength each' to the other with the result that a strong anddurable frameis produced.

In addition to the frame referred to, the wrench comprises a shaft 12,of circular form in cross section, the ends 13 and 14 of which are ofangular form in cross section. On the inner angular end 13 of the shaft12 is removably arranged an interiorly angular portion of a socketmember 15, and in the angular aperture 9 is arranged the exteriorlyangular portion of a socket member 16, Figures 4 and 11. At their inner.opposed portions the said socket members are interiorly angular inorder to engage the head of a bolt and a nut on. the bolt, respectively,after the manner shown in Figure 1. Being removable the socket members15 and 16 are adapted to give place to socket members of different sizesand shapes of which any desired number may be furnished in a kit.

Surrounding the shaft 12 and interposed between the abutment furnishedbythe enlargement of the end 13 and a washer 17 on the shaft at the innerside of the arm 4 is a coiled sprin 18, the function of which is toyieldingly thrust the shaft 12 toward the arm 8 of the bar 2.

The manner of using the wrench as thus far described will be readilyunderstood by reference to Figure 1, and need not therefore be enlargedupon. I

The shaft 12 is equipped with a removable T-handle 19, said handlehaving an angular aperture 20 to receive the angular end 14: of

the shaft. It will also be noticed in this connection that in one sidethe said angular end 14: has a socket 21, and that the handle 19 isprovided with a pin 22 adapted to enter the said socket 21 and therebyremovably fasten the handle 011 the shaft. The pin is mov able throughthe aperture in one wall of the angular aperture 20 and is connected adjacent to its outer end to an intermediate point in a spring rod 23.Preferably the saidrod 23 is extended through a. diametrical aperture inthe outer end of the pin 22, Figures 8,

9 and 10, and said spring rod 28 is arranged in a groove 24: in oneedgeof the handle-l9 and ,is fixedly connected at one end of the said handle19 as indicated'by 25. The opposite end of the spring rod 28 is providedvith an arm 26. This arm extends loosely througha'bore 27 in the handle19 and is de signed to rest at its free end in a recess 28 formed in theedge of the handle opposite to theedge at which the rod 2-3 is disposed.Manifestly by pressing with a thumb on the free end of the arm 26 theoperator is enabled to move the pin 22 outof the socket 21 in the handleend let, whereupon the handle 19 may be slipped off the end ll of theshaft 12. It also follows that the'handle 19 may be ex peditiouslyapplied to and detachably fastened on the end le of the shaft 12. InFigure 6 I illustrate the manner in which the shaft 12, the T-handle 19and one of the socket members 15 or16 may be usedto form a socketwrench, andin Figure 7 I show that the said elements plus a .screwengaging member 30 my be used to form an efficient screw driver. i

The angular end 13 of the shaft 12, and

the angular aperture 9 in the angular arm 8 are so constructed that anystandard socket member canbe used in connection with the improvedwrench.

It will be apparent from the foregoing that my novel wrench isespecially adapted for removing the bolts from automobile housings anddifferential casings, inasmuch as the wrench enables a single workman todo the work without the help of an assistant or assistants.

Having described my invention, what I claim and desire to secure byLetters-Patent, 1s

1. A wrench comprising a frame made up of lapped bars one of which isprovided with other of which is an angular aperture alined with theclrcular aperture, a headed and.

threaded boltextending through the slot and aperture of the lapped bars,and a nut mounted on said bolt; a shaft of circular form in crosssection arranged in the circular aperture of one arm of the frame andhaving an eXteriorly-angular inner end, a spring surrounding the shaftand interposed between said cXteriorly-angular end thereof and one ofthe frame arms, a handle detachably fastened on the outer end of theshaft, and socket members, one removably arranged in the-angularaperture of the frame and the other removably arranged on theeXteriorly-angular end of the shaft, said wrench capable of disassemblyfor convenient carriage in a tool box; I

2. The combination with a shaft havingan angular end and a socket in onesideof said end; a handle having an angular aperture receivingtheangular end of the shaft and also having a longitudinal groove in one ofits edges and a bore extending from one end of said groove to theopposite edge of the handle and further having in said opposite edge andin communicationwith the bore'a recess, a pin movablethrough an aperturein one wall of the angular aperture in the handle and adapted toenterthe socket in the shaft, and a spring rod connected at one end to thehandle in the groove thereof and.

extending through an aperture in the pin andhavlng at its free end anarm extendlng through the bore in the handle to the recess in theopposite edge of the handle.

In testimony whereof I affix my signature.
